FPS Games are usually centered on a combat game play where the player plays through a first-person perspective as the in-game character, in order to strike the opponent in accordance with each level's objective. In such type of game play, the decision making that leads the player to take certain actions is carried out based on the player's visual cognitive information, and information collected both directly/indirectly via previous game play experiences. Particularly in the case of a FPS game where the mutual interaction between the player and each game level is the key, an analysis of a FPS game player's visual cognitive information can provide intelligence which can help design or adjust structures of a game level. For this thesis, a sample group has been collected and divided into a novice group and an expert group based on their level of experience with FPS games. Then, using eye-tracking equipments, the point of gaze of players in each group were recorded whilst they were playing levels of a well-known FPS title. The point of gaze in the moment the player starts to take actions -right before/after the start of a combat- was recorded in 500 play videos, and as a result each group's intrinsic pattern of gaze could be identified. Through these results, the author plans to develop a methodology that can enhance the difficulty setting and the playability of FPS game levels.

Current Internet and Intranet developments are focusing on network multimedia services involving the transport of real-time multimedia streams. In this paper, we present a real-time MPEG2 Encoding/Decoding systems and a MPEG2 stream player running on client systems based on real-time transport protocol(RTP). The MPEG2 player has been implemented by using JMF and java applet. We have tested our prototype systems with one of possible multimedia sources, camcoder, to verify its functional correctness and measure its performance.

온라인 게임(online game)은 초고속 통신망의 보급과 기존의 1인용 게임(Single-player game)의 인공지능에서 느낄 수 없었던 즐거움을 제공함으로써 급속도로 보급되었다. 또한 최근의 온라인 게임 시장은 그래픽 기술을 비롯한 하드웨어의 발달로 2D에서 3D로 옮겨가고 있다. 따라서 이러한 추세에 따라 온라인 게임은 보다 많은 멀티미디어 데이터를 필요로 하게 되었다. 이에 Multimedia Storage Sever를 멀티플레이어 온라인 게임(Multi-player online game)에 적용함으로써 보다 효율적인 멀티플레이어 온라인 게임 서버를 구성하고자 한다.

We report that the optimum substrate temperature to fabricate a-Si:H $n^+-p-p^+$ cell decreases with increasing the boron concentration in the Player. The results can be explained as the dependence of substrate temperature for the relaxation of silicon atoms and the bonded hydrogen concentration in the player.

As the functionality of portable devices arc being enhanced and the performance is being greatly improved, power dissipations of battery driven portable devices are being increased. So, an efficient power management for reducing their power consumption is needed. In this paper, we propose a window-based DVS algorithm for MPEG Player. The proposed algorithm maintains the recently frame information and execution time received from MPEG player in window queue and dynamically adjusts (frequency, voltage) level based on window queue information. Our algorithm can be implemented in the common multimedia player as a module. We employed well-known MPlayer for the measurement of performance. The experimental result shows that the proposed algorithm reduces energy consumption by 56% on maximal performance.
